FIELD STRUCTURE OF LINE INDUCTION MACHINE Russian patent published in 1998 - IPC

FIELD: line induction machines. SUBSTANCE: the device has toothed magnetic core 1 and three-phase winding including concentric (4) and ring (5) coils. The phase winding that is middle relative to the lateral axis of the field structure uses ring coils 5, whose active sides are located on the bottom of grooves 3 that are extreme ones for given phase q, where q - the member of grooves per pole and phase. Extreme concretic coils 4 of the other phases are positioned in the upper layer of grooves 3. EFFECT: improved design. 1 wdg
